A locked-room mystery is solved by detective Fleming Stone. Sanford Embury refused to give his wife an allowance of spending cash or even a checking account. He pays all the bills and her store charge accounts. "Eunice found it intolerable to be cramped and pinched for small amounts of ready cash, when her husband was a rich man." Sanford is found dead in bed, alone, with the door of his second-story bedroom bolted shut from the inside. Was his wife a party to the murder, or perhaps did she commit the murder in a fit of rage?
